Spectroscopic analysis of the copolymerization achieved via slow cooling monomers. (a) Schematic representation of the experiment performed. (b) CD cooling curves (λ = 341 nm, cooling rate = 15 °C h–1) of poly[(S-1)0.5-co-(S-2)0.5] (decalin, ctot = 50 μM) (blue line), poly(S-1) (red line), poly(S-2) (green line), and the linear sum of [poly(S-1) + poly(S-2)] assuming no interaction (decalin, cS-1 = cS-2 = 25 μM) (black dotted line). (c) CD spectra of poly[(S-1)0.5-co-(S-2)0.5] recorded while cooling (cooling rate = 15 °C h–1) and copolymerizing. Spectra acquired every 5 degrees from 100 °C (red line) to 40 °C (blue line).
